SPECIFICATION forming part of Letters Patent No..380,119. dated March27, 1888.

Application filed September 29,1887. Serial No. 251,014. (No model.)

To all whom it may concern.- f-

Be it known that we, SAMUEL V. KENNEDY and CHARLES A. ANDERSON, ofMinneapolis, Minnesota, have invented certain Improvements inGrain-Binders, of which the following is a specification. l

This invention relates to that'class of binders in which the packersremain at rest during the binding operation and resume their labor atthe completion thereof. It embraces the hereinafter-described devicesfor accomplishing'this resultina simple, positive, and effective manner;also the hereinafterdescribed construction ofthe compressor-shaft anditsaccessories,whereby the said shaft and its accessories areappropriately associated and the shaft provided with bearings in theframework of the binder with a small amount of labor, and also theemployment of the compressor-shaft as a torsion-spring, by which theordinary compressor-spring is dispensed with.

Figure 1 is an elevation of abinder embody.- ing this invention, lookingfrom the stubble side. Fig. 2 is an elevation of the same looking towardthe rear of the machine, with the parts shown in their proper positionwhen the binder is at rest and the packers in operation; Fig. 3, thesame view with the binder in operation and the packers at rest, thepackers and some other partsbein g omitted to more clearly show theother features; Fig. 4, details of the pinion which drives the binder;Fig. 5, a continuously-running sleeve or shaft from which the binder andpackers take their motion; Fig. 6, the packer-shaft with thepacker-cranks omitted; Fig. 7, a sprocket-wheel which communicatesmotion to the sleeve 6.

Ido,i:r,-l0,.and is rotated by the engagement ofl the drivingdog 10 witheither'one of the rollwhich a set-screw in the trip-arm 14 bears toactuate the same.

15 is a crank-arm on the needle-shaft 12,

which,by means of the pitman 16,is connected to a wrist-pin on the maingear 2.

17 is the compressor, and 18 the compressorshaft, connected and operatedin the usual `manner by the crank 19, connecting-rod 20,

quadrant 21, and main binder-gear 2.

22 are packers'rnounted upon cranks 23 on the packer-shaft 24 and havingtheir-lower ends or extensions, below the cranks 23, connected by thelinks 25' to a rock-shaft, 26, whichserves to trip the binder throughthe medium of the set-screw and trip-arm 14, as shown. A y

locking-dog,27,acting upon the cam 28 on thev main gear 2, serves tovgive the said gear 2 a l slight impulse forward and hold the samepositively in position after the dog 10 of the pinion 5 has beendisengaged from the driveroller 8.

The parts thus -far described are in many respects substantially thesame in construction and mode of operation as the similar parts in thewell-known Appleby binder, and further explanation thereof in detail istherefore unnecessaryybut it will4 be observed that the binder-drivingshaft 6, as before explained, is hollow and contains the packer-shaft24, which is provided with bearings, as shown, at each end thereof. Thepacker-shaft 24 has affixed to i its forward end the head 29,provided'withthe two quadrantal iianges 30, whose peripheries areconcentric with the shaft A24. Tothe head 29 is pivoted a double-enddriving-dog, '31, ywhich is thrown into working position by the spring32, so that one` of the rollers 9 on the continuously-running shaft 6will engage with the heel 33 thereof, and thereby drive the roopacker-shaft 24. The drive-dog 31 has two cam-faces, 36, the functionsof which will be hereinafter referred to.

34 is a stop-dog for the packers. It is sleeved or pivoted upon theneedle-shaft between the crank 15. and the binder stop-dog 11 and has atits lower end a, rearward bend, 35, which, by collision with thepacker-driving dog 3l, at the appropriate time disengages thedriving-roller 9 from the heel 33 of the dog 31, and thus stops thepackers. ilo the hub of the packer stop-dog 34 is aiixed anupwardlyprojecting arm, 37, the free end of which is adapted to engagewith the recessed lower end of the arm 38, extending downwardly from thehub of the locking-dog 27, as shown. Aspiral spring, 39, serves toactuate the locking-dog 27 in the usual manner.

In operation, when the packers are at work and while the binders are atrest, as shown in Fig. 2, the binder drive-dog 10 bears against thebinder stop-dog 11, which depresses the heel of the drive-dog 10, sothat the driveroller 8 may pass outside thereof, the binder being lockedin position by the locking-dog 27 and cam 28, allin the usual manner.While the driving head 7 is being continuously driven in the directionshown by the chain and sprocketwheel, the bearing of one of the rollers9 against the heel 33 of the packer-driving dog 31 drives the packers.When the gavel is collected, the binder is tripped into gear by theaction of the packers through the links 25, rock-shaft 26, trip-arm 14,and heel 13 on the stop-dog 11,whereby the stop-dog 11 is raised fromcontact with the longI arm of the drive-dog 10 on the driving-pinion 5.The dog,being thus released, is thrown by its spring into position to beengaged and rotated by one of the drive-rollers 8, whereby the binder isset into operation in the usual manner. When the main binder-gear 2 hasmoved ashort distance in the direction indicated, the upper end of thelocking-dog 27 is released from the cam 28 and is thrust upward by therecoil of its spring 39. This swings the arms 38 and 37 outwardly andcarrries the packer stop-dog 34 inward toward the packer-shaft until thelower end of the dog comes in contact with and rides upon the peripheryof one of the quadrantal anges 30. Before this arm passes oi the saidflange, the end of the packer-driving dog 31, by'acquiring contact withthe rearward projection, 35, of the stop-dog34, is rocked upon itspivot, which depresses the heel orshorter arm, 33, thereoi` anddisengages the same from the driving-roller 9, thus stopping the packersin substantially the same manner as that in which the binder is stopped.When the drive-dog 31 has been arrested in its movement by contact withthe stop-dog 34, and the flange 30, with the roller 9, has movedforward,

so that by the rocking upon its pivot of the drive-dog 31 its heel 33has been depressed suciently to allow the drive-roller 9 to pass outsideof it, an opening is presented between the cam-face 36, Fig. 3, and therear surface of the flange 30. Into this opening ythebend 35 of thestop-dog 34 is carried by the force derived from the spring 39, and asthe bend 35 moves down the inclined cam-face 36 it further depresses theheel 33 of the dog 31, so that the heel 33 is carried out of the path ofythe drive-roller 9, thus preventing any contact between the said roller9 and the dog 31 until the latter shall have been released by the actionof the cam 28 on the locking-dog 27 at the completion of the bindingoperation, when the binder comes to rest and the packers resume theirwork, the parts being then in the position in which they are representedin Fig. 3. The dropping of the bend 35 of the dog 34 in the openingbehind the ilange 30, as described, locks the packer-shaft against anybackward movement after the driving devices have been disengaged, whichbackward movement might otherwise ensue from the pressure of grain whichhas been packed into the gavelreceptacle, the packers being purposely soarranged and timed that they will stop and hold the accumulated gavel ata point in advance of the needles path, and thus relieve the needle fromthe labor of penetrating the mass of grain. Y

It results from the inclusion in this organization of stopping andlockingdevices of the cam-faces 36 for engagement by the bend 35 of thestopdog 34 that the organization is not prevented from being practicallyeffective by the ordinary wear of the connections in continued use, forif in the course of time there is any looseness or lost motion from thiscause the bend35 is simply forced to move farther down upon the cam-face36 and to thus rock the dog 31 to its proper position in all cases.Adjustment to compensate for wear is thus rendered unnecessary by makingthis stopping and locking organization practically self-ad justing.

Another important feature of the organization is its quickness ofaction. The stop-dog 34 is actuated the instant the main binder-gearbegins to move, and hence the packers are stopped promptly before theneedle can be projected above the deck to interfere with their action. i

The drive'dog 31 is made double, so that either of its opposite ends maybe acted upon by the bend 35 of the stop-dog 34, in order that either ofthe two packers may be stopped and made to'hold the accumulated gavelforward of the needle accordingly as either packer may be nearer thegavel when the binder is tripped into gear.

It is of course not new to stop the packers by means of a cam on themain binder-gear. The novelty herein consists in the describedcombination of devices whereby either one :of the two packers may-bestopped and locked rigidly to hold the accumulated gavel in suchposition that the needle makes its movement behind rather than throughthe mass of grain composing the gavel.

The compressor-shaft 18 is made of a square IIO bar of spring-steel..The hub h of the compressor 17 and the hub h of the crank-arm are eachmade with a square central opening to fit the shaft 18, and are seatedin bearings in the binder-frame, as shown in Fig. 1, in which gure aportion of the binder-frame near the compressor is represented as brokenaway to show the construction. The compressor-shaft 18 is made of suchsize that its torsional elasticity will provide all the elasticityrequired for the compressor, so that the cumbersome coiled-spring deviceheretofore used for the compressor is dispensed with. By this conrstruction all machinework is avoided, excepting the drilling` of acotter-hole in each end of the shaft 18. The latter is simply cut-fromcommercial steel bar, drilled as above, put in its place in thebinder-frame, the compressor and bell-crank put on, as shown in Fig. 1,and the cotters put in to hold the compressor and crank-arm in place. Y

What is claimed as the invention is 1. In a grain-binder, thecontinuously-running hollow shaft 6, the drive-head 7, the rollers 8 and9 on opposite sides thereof, thestopdog 11 and the locking dog 10, adriving sprocket-wheel adj ustably mounted upona square part ofthe shaft6 to drive the same, the packer-shaft 24,' mounted within the hollowshaft 6, the driving-head 29 and drivingdog 3l thereon, the stop-dog 34,the arms 37 and 38, locking-dog 27, the spring 39, and cam 28, wherebythe binder when stopped is locked in position and the packers'started,and whereby the packers are stopped and locked in position by thestarting ofthe binder, in the manner set forth.
